中文摘要：
采用粒子图像测速仪对介质阻挡放电等离子体在静止流场中诱导出的速度场、等离子体激励对平板附面层的改变进行了研究.实验结果表明,等离子体激励作用主要集中在近壁面附近;激励电压与诱导速度近似为线性关系,激励频率对诱导速度的影响不大.将等离子体流动控制原理初步归纳为撞击效应和热效应,并通过数值模拟的方法研究了热效应对等离子体激励诱导速度场的影响.数值模拟结果表明,在无来流的情况下等离子体热效应对流场的影响比较明显,使局部水平方向速度大小提高近30%.简要介绍了提高等离子体激励强度的方法.
英文摘要：
Flow field induced by the plasma actuator in quiescent air was measured by particle image velocimetry system. Boundary layer flow control in fiat plate by the plasma actuator was investigated experimentally. Experimental results showed that the relation between exciting voltage and induced velocity magnitude was linear, but the influence of supply frequency was not evident. Mechanisms of plasma flow control were preliminarily ascertained to be results of collisions and temperature increase. Numerical simulation results showed that the thermal effect of the plasma was evident without incoming velocity. Methods of increasing plasma actuator＇s intensity were introduced briefly.
